GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 361,674, dated April 26, 1887.

Application filed November 18, 1886. Serial No. 219,274. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE K. COOKE, a citizen of theUnited States, residing at New York, in the county and State of New York, haveinventedanew and Improved Gas Burner, of which the following is a specification.

This invention relates to that kind of gasburners in which a small secondary burner is placed alongside of the main burner, a small flame being kept burning in the secondary burner when the gas is turned off from the main burner. \Vhen the supply to the main burner is turned on, the flame from the secondary burner ignites the gas, and thus the main burner can be lighted at any time without a match.

The invention consists in the various fea tures of improvement hereinafter more fully pointed out.

In the accompanying drawings, Figure 1 is a vertical central section of my improved gasburner. Fig. 2 is a side view of the valve.- plug. Figs. 3 and 4 are side views of the sleeve 2'. Fig. 5 is a vertical central section of theburner,showing the main burner turned off.

The letter a represents the main burner, and b the secondary burner, placed side by side and entering at their lower end a tapering valve-seat, 0, adapted for the reception of the tapering plug-valve (Z. The lower side of the valve-seat o is entered into by the supply-pipe 6, having abranch, f, that also enters the valveseat. The secondary burner b is shorter than the main burner a, and thelatter is surrounded by a mica chimney, 9, into which the secondary burner 11 enters, while the main burner projects above such chimney, as shown. The mica chimney is covered by a perforated cap, h, that permits the products of combustion from the burner to escape.

Within the valve-seat 0 there is placed a tubular sleeve, "5, preferably made of brass and embedded snugly into the metal of the valve; seat a. This sleeve 2' is introduced into the mold in which the valve-seat is cast, and in this way I obtain a tight fit for the valve-plug d without boring out the interior of the valveseat. I

A small portion of the sleeve i is cutaway, as shown at Fig. 4, said cut-away portion being filled up in the process of castingby the metal from the valveseat, and thus said sleeve is properly locked in place and is prevented from working loose. Four holes are made in the sleeve i, to register with the burners a b and with the pipes e f.

The valve-plug d is provided with one straight transverse perforation, k, in line vertically with the parts a 6. It is also provided with a groove, m, partly encircling the plug 01 and in line with the secondary burner b and branch f, so as to connect the parts and conduct the gas from the branch into the secondary burner. The groove in communicates by a spiral groove, Z, with the perforation 7c.

The operation of the parts is as follows: When the supply from the main burner is turned off, the gas will enter from pipe f through groove m to burner b, Fig. 5; but when the valve d is turned to bring perforation It in line with the parts a e, and to thus permit the gas to enter the main burner, the burner b will be cut Off from branch), and the gas from such branch will enter through the groove 6 into the main burner a, and will aid in maintaining the flame.

I am aware that it is not new in gas-burners of the general character herein described to employ a valve-plug having an aperture diametrically through it adapted to register with the main burner and a supply-pipe when the main burner is turned on, said plug also having an oblique groove leading from said diametrical aperture to a groove adapted to register with the secondary burner and an offsetpassage, f, when the main burner is turned off. I am also aware that in faucets it is old to apply bushings to form smooth valve-seats in the body of the valve. I therefore broadly disclaim such devices.

What I claim is 1. The combination of burners a and b and pipes e f with the conical valve-seat c and infour points, cut away at j, and embedded into I0 closed perforated tubular sleeve 1', having cutthe metal forming the body of the burner, away portion j, and with the perforated plugand a valve-plug, d, having gas-passages 70 Z, in valve d, having grooves Z m, substantially as and fitted into said sleeve, substantially as de- 5 specified. scribed.
